5k hours can be half life, or can be plumb worn out depending on how it was maintained. The 4wd system defaults to engaged, make sure it pulls itself out of 4wd and works otherwise. Check Dual Power if so equipped, and be sure it hasn't been ran with the emergency brake engaged - will fill up the hydraulic system with trash if so. Watch the PTO and brake for correct function.
That's a gray market tractor if it matters to you, to my knowledge all 7910's were originally intended for the European market.
